I can just imagine the game warden getting a call:
"Sir...can you tell me how you define a flu flu."
Warden: "Hold on sir"...."Hey Fred, there's another guy on the phone asking about flu flu arrows...what should I tell him?"
Fred: "Tell him the can only have single bevel field points, and that the feathers must be totally symetrical, but must be altered from arrow to arrow...you know, shield shape on one arrow, parabolic on the other. Oh yes...and they can only have yellow or white feathers, but pink is okay on Saturdays."
Warden: "Gotcha!....You would think these guys never saw a flu flu arrow in their life. I wonder if we should tell them that they have to be a certain length and weight as well? How about a fake section in our field manual (he he), Section 11, Paragraph 3, Sub Paragraph 2B, says (ha ha)."
Fred: "Oh yeah....and while you have them going, tell them that they can only be carried in a State approved back quiver made from recycled leather. By the way, what is our rules regarding flu flu arrows?"
Warden: "We just copied the lines from a Roy Hoff article in Archery Magazine, from 1956. That seemed to make the most sense. Heck we have no clue...big feathers maybe? We can freak them out though by carrying a tape measure with us when we check their arrows."
Warden getting back on phone: "Sir...can you please leave your phone number and I will call you back. I seems we are updating our files as of this hour and their will be a multitude of changes regarding said arrows, regarding measurements, weights, colors, manufacturing specs, et al. We should have it settled by the end of season for sure."
